DON'T FORGET to bring your dual-band handheld transceiver to 
the AMSAT-DC gathering.  And don't forget to remind yourself how 
to program a split offset before you leave home (check the 
manual).  If you do this you may be glad.  See again Tom K3IO's 
message below.  

TX 435.900 MHz FM
RX 144.350 MHz FM

C U soon,
